The symbolism of "seven" should be traced back to the symbolism of its component elements, "three" and "four," which represent divinity and humanity. Hence, "seven" represents the union between God and man. Among the Persians, the Greeks, the ancient Indians, the Romans, and all nations where seven days in the week were recognized, the influence of the number seven prevailed. It was called by Cicero "the knot and cement of all things," because in "seven" the spiritual and natural world were comprehended in one idea. Some writers claim that the Hebrews borrowed it from their heathen neighbors. The Sabbath, being the seventh day, suggested seven as the appointment for all sacred periods. The seventh month was ushered in by the Feast of Trumpets; seven weeks was the interval between the Passover and the Pentecost, and so on, recognizing seven as the symbol of all connected with the Divinity.
